RTAX2000S-LG624V - 2M-Gate Rad-Tolerant FPGA | Microchip
MPN: RTAX2000S-LG624V ✓ Hoạt độngRTAX2000S-LG624V Tóm tắt
A radiation-tolerant FPGA is a field-programmable gate array engineered to survive the ionizing radiation environment of orbital and deep-space missions. Within the semiconductor hierarchy, it sits under programmable logic devices alongside standard FPGAs, but adds single-event and total-ionizing-dose tolerance that commercial parts lack. RTAX-S devices are one-time-programmable and live at power-up, making them a drop-in alternative to custom radiation-hardened ASICs for many payloads.
Key features include highly reliable nonvolatile antifuse technology, up to 684 user I/Os, up to 540 kbits of embedded SRAM with optional EDAC protection, total ionizing dose tolerance of 300 krad (functional) and 200 krad (parametric), and single-event upset rates below 1E-10 errors per bit-day. These figures, taken from the Microchip RTAX-S/SL and RTAX-DSP datasheet, make the device suitable for missions where reconfiguration is not required but immunity to configuration upsets is essential.
Architecturally, the RTAX-S family is based on the commercial Axcelerator fabric, using segmented clock structures, chip-wide highway routing, and embedded FIFO control logic. The antifuse interconnect is programmed once at the board factory and is inherently SEU-hard at the configuration level, unlike SRAM-based FPGAs that require scrubbing. The LG624 designation indicates a ceramic lid package qualified for screening in space-grade flows.
Typical applications include satellite payload data processing, spacecraft bus control and telemetry, sensor interface and image-processing chains on orbiters, and guidance electronics on launch vehicles. Designers choose RTAX2000S when logic density of about two million gates must operate for years under radiation without configuration errors.
A critical design consideration is that RTAX-S devices are one-time-programmable: verify the design thoroughly on a reprogrammable prototype such as the Aldec ACT-H3K-CG624 adaptor before programming flight units.

Ứng dụng tiêu biểu
RTAX2000S-LG624V phù hợp cho 6 Áp dụngs: Satellite Payload Data Processing, Spacecraft Bus Control and Telemetry, On-Board Image and Sensor Processing, Launch Vehicle Avionics, Radiation-Hardened ASIC Replacement, Deep-Space Instrumentation and SmallSat Logic.
Satellite Payload Data Processing
The RTAX2000S-LG624V fits payload processing chains on low-earth-orbit and geostationary satellites because its 2,000,000 equivalent gates and 32,256 logic cells absorb high-throughput framing, compression, and error-correction functions in a single chip. Its antifuse configuration is inherently immune to configuration upsets, with SEU rates below 1E-10 errors per bit-day, eliminating external scrubbing hardware that an SRAM FPGA would require. Embedded SRAM up to 540 kbits with optional EDAC supports FIFO buffering between imaging sensors and downlink modulators. Placed directly behind the sensor front end, it runs at live-at-power-up so payload data flow begins without a boot sequence, improving availability during short eclipse-limited observation windows.

Spacecraft Bus Control and Telemetry
Spacecraft on-board computers and telemetry formatters benefit from the RTAX2000S-LG624V's live-at-power-up operation and 300 krad total ionizing dose tolerance (200 krad parametric), which covers multi-year bus controller missions in medium-earth orbits. The up-to-684 user I/Os interface mil-std-style buses, UARTs, and redundant sensor channels without external glue logic, while segmented clock structures allow independent clock domains for the processor interface and housekeeping functions. Because the antifuse fabric never loses configuration, watchdog and safe-mode logic remain available even after single events, a critical property for recovery electronics that must operate reliably through the full mission lifetime without ground intervention.

On-Board Image and Sensor Processing
Hyperspectral imagers and star trackers need deterministic, radiation-tolerant pre-processing close to the detector. The RTAX2000S-LG624V provides 21,504 CLBs and 540 kbits of embedded SRAM with optional EDAC, enough for pixel correction, windowing, and first-stage convolution directly at the focal plane. The chip-wide highway routing supports wide datapaths between acquisition and compression blocks at low skew. Because the die is one-time-programmable, the fixed processing pipeline is locked at integration, avoiding the possibility of an on-orbit configuration error corrupting science data; verification is completed on an Aldec ACT-H3K-CG624 reprogrammable adaptor before flight units are programmed.

Launch Vehicle Avionics
Guidance, sequencing, and flight-termination electronics in launch vehicles experience intense vibration and brief but high-dose radiation events. The RTAX2000S-LG624V's ceramic CG624 column grid array package withstands mechanical stress typical of booster environments, and its antifuse technology survives TID events up to 300 krad (functional) without configuration loss. Live-at-power-up behavior guarantees sequencer logic is active the moment vehicle power is applied, with no configuration load time that could delay ignition-critical sequencing. Designers use its 684 user I/Os to consolidate redundant sensor voting, actuator drivers, and flight-event counters that previously required multiple rad-hard ASICs.

Radiation-Hardened ASIC Replacement
The RTAX-S family is positioned by Microchip as a radiation-tolerant alternative to radiation-hardened ASICs. Where an RH-ASIC requires an NRE mask set, long foundry lead time, and large minimum orders, the RTAX2000S-LG624V delivers about 2,000,000 system gates as a catalog device with 300 krad functional TID tolerance and SEU below 1E-10 errors per bit-day. The same Axcelerator-derived fabric allows the RTL proven on commercial ProASIC3 prototyping boards to compile directly to the flight part. For low-to-medium volume missions, this cuts schedule risk dramatically while preserving single-chip form factor, low static power, and true live-at-power-up behavior.

Deep-Space Instrumentation and SmallSat Logic
Deep-space probes and radiation-exposed smallsats encounter cumulative doses beyond LEO environments; the RTAX2000S-LG624V's 300 krad functional TID tolerance and antifuse fabric make it a common choice where commercial FPGAs fail within months. The 32,256 logic cells implement instrument sequencers, ADC interface logic, and CCSDS-compliant packetization, while embedded EDAC-protected SRAM safeguards accumulated science data between downlinks. Power budgets on solar- and RTG-limited missions benefit from the low static consumption of antifuse technology, which draws no refresh current unlike SRAM configuration arrays, extending available power margin for instruments during cruise and encounter phases.

Ghi chú thiết kế
RTAX-S antifuse FPGAs are one-time-programmable: once programmed, the device cannot be corrected. Always complete functional, timing, and radiation-margin verification on a reprogrammable platform first - the Aldec ACT-H3K-CG624 adaptor emulates CG624-package RTAX devices up to RTAX2000S capacity using flash-based ProASIC3E technology, per the joint Microchip/Aldec prototyping flow. Programming flight units before design freeze risks scrapping expensive space-grade parts. Reserve at least 20% of logic and I/O resources for late requirement changes that cannot be patched on-site.
The CG624 ceramic column grid array requires controlled-impedance PCB stackup and reflow profiles qualified for ceramic column packages; verify column coplanarity and board warpage limits before assembly. Note from the Microsemi datasheet that RTAX2000S/SL and RTAX2000D/DL are not pin compatible in CQ352-type packages, so lock your footprint to the S/SL pinout definition in the RTAX-S/SL datasheet before routing. Provide generous fanout vias under the 624-column array and follow the manufacturer's land-pattern recommendations exactly, since rework of a CCGA joint is not practical on flight hardware.
Because the antifuse configuration draws no configuration-refresh current, static power is inherently low compared with SRAM FPGAs - useful for eclipse and RTG-limited power budgets. However, dynamic power scales with clock frequency and switching activity across the 32,256 logic cells; perform a power estimate in the Microchip design tools before finalizing the rail sizing, and budget margin for worst-case temperature corners. Decouple all supply pins with low-ESR ceramics placed close to the CG624 power columns. Exact supply voltage values should be taken from the RTAX-S/SL datasheet electrical tables.
